To all whom it may concern:

Be itknown that I, JOHN W. SURBRUG, a citizen of the United States, and a resident of the city of Montclair, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Mouthpieces for Cigarettes and the Like, of which elements.

the following is a specification.

The object of my invention is to produce in a simple and efficient manner, a mouthpiece or evice to be inserted in the smoking end of a cigarette or other like article, which will readil absorb from the tobacco and paper smo e or other products of combustion, considerable if not all of ,the harmfu My invention consists in the article of manufacture herelnafterdescribed, and in its structural combination with a cigarette or like article, likewise as hereinafter dc.-

. scribed and more fully pointed out in the claims appended hereto.

- vice as hel In the drawing forming part of this specification in which I have shown an embodiment of my invention, Figure 1 is a side elevation, very much enlarged, of a cigarette embodying my improvements, a portion of the outer tube or covering bein broken away to disclose a part of the interlor. Fig.

2 is a like view, partly in section, the sect1on being taken transversely through the longitudinal center of the cigarette. Fig. 3

is a like view showing the exterior of the cigarette provided with my improvements, the interior constructionbeing indicated by dotted lines. Fig. 4 is an end elevation, fur

S1m1lar numerals of reference indicate like parts, throughout theseveral views.

' My inventionun its broad aspect consists in roviding a plu or like device which is toe inserted within the body or tube of a cigarette or the like, to intercept the passage of the smoke or products of combustion, the characteristics of which are that it is transversely corru ated so as to produce,

when it is inserted wlthin the tube of a cigarette, a series of channels through which the smoke or products of combustion may readily pass, and which I preferably make of some absorbent material such a pulpy uncalendered paper. My improved plug may, I

therefore, be employed in various ways. It may be made up separately and sold for use on cigarettes, pipes, and on varied forms of smoking devices, or it may be as hereinafter shown, retained within a plug holder and it and the holder inclosed within the tube of a cigarette.

In the drawing, 2 indicates a cigarette comprising an outer tube 3 of combustible material such as paper, an interior rod 4 of tobacco, a plug holder 5 of the desired length held within the tube 3 and the plug 6 held within the holder and preferably as located in Fig. 2, a short distance from the 1nouthend of the cigarette so as to keep the tongue of the smoker coming in contact, as much as possible, with the plug.

As shown in Fig. 5, the preferred form of plug 6 is in the shape of a strip of paper 7 or other desired material provided with longitudinal corrugations which form elevations 8 and depressions 9 therein. This strip of paper, of suflicient length, is preferably folded overupon itself, as indicated at 10, Fig. 5, so as to produce two plies of material, and then rolled upon itself with the fold 10 centrallyv located so as to form a plug as indicated 411 Figs 2 and 4. This plug is placed within the holder which comprises a strip of paper 11, spirally disposed upon itself as se en in Fig; 1 so that the free end of the strips 7 may spring out and engage the'interior of the holder 5 with suf-' ficient friction to retain the plug in its proper position in the holder. The outer tube 3 of the cigarette is formed about the tobacco rod and theplug-holder 5 1n any manner well-known in the art of making cigarettes. This disposition of the strip of material of which the holder is madecausing it'to sprin out and be retained by the friction of its ree end against the inside of the said tube.

As indicated in Fig. 2, the products of combustion pass through the interior or bore 12 of the holder 5 and thence through the channels 13 formed in the plug by the overlapping and overlying of the indentations or corrugations in the body of the material of which the plug is composed, which channels, as shown in Fig. 2, lie in the direction of the. length of the cigarette, the products of combustion leaving the same as indicated in Fig. 2.

It will be noted by reference to Fig. 4 that by reason of the spiral disposition of the material of which the plug is made, the same has sprung out to a greater extent at the center than at the circumference, thereby leaving a somewhat lar r opening, as shown at 15, at the center the plug than if removed from the center. This insures a central draft which is highly desirable as producing an even burning of the ci arette without lmpairing the special function of the plug of separating into numerous small .streams the products of combustion, and

preferably simultaneously absorbin the absorbent elements thereof. The in tiplicity of independent channels thus forme in the mouth-end of the cigarette, which while large enough to permit of a suflicient draft, are small enough to retain the heavier particles of carbon, etc., thereby performing the additional function of straining the smoke before it passes out of the cigarette.

It is clear that my invention ma be embodied in various ways without d eparting from its spirit, and particularly that it is not essential thatI employ two overlying strips of material to form the plug, or that the channels be formed by corrugating the within said tu surface, as a single strip of material may be emdployed and the channels otherwise forme c Having described my invention, I claim:

1. As an article of manufacture, a plug for cigarettes and the like, com rising a strip of material folded over on to itself and rolled into the plug with the line of the fold centrally located.

2. As a product of manufacture, a plug for cigarettes and the like, comprisin a strip of material folded over upon itsel to constitute a double ply, said double ply be-. ing rolled .upon itself, and said strip having an opposite or broken surface.

3. In a cigarette or the like, the combination. of an outer tubular covering, of a plug comprising a strip of corrugated material folded over on itself and rolled into the plug with the line of the fold centrally located said ping being frictionally held Signed at the city, count and State of New York, the 1st day of e tember, 1909.
